Understanding the Basics of Square Roots

Before diving into the square root of 155, it's important to have a basic understanding of what square roots are. A square root is a number that, when multiplied by itself, results in the original number. For example, the square root of 16 is 4 because 4 x 4 = 16. Square roots are denoted by the symbol √. When we see √155, we are looking for a number that, when multiplied by itself, equals 155.

Calculating the Square Root of 155 Using Long Division

One way to find the square root of 155 is by using long division. To do this, we start by grouping the digits of 155 into pairs, starting from the right. We add a zero if necessary to make sure we have an even number of digits. In this case, we group 15 and 5. We then find the largest perfect square less than or equal to 15, which is 9. We write the square root of 9, which is 3, above the first pair of digits. We subtract 9 from 15 and bring down the next pair of digits to get 56. We double the current digit, which is 3, to get 6. We then guess a number that we can multiply by the current quotient (3) and the doubled digit (6) to get a product less than or equal to 56. That number is 4. We write 34 below 56 and subtract to get 22. We bring down the next pair of digits, which is 00. We double the current quotient, which is still 3, to get 6. We guess again and get 5 as the quotient. We write 355 below 220 and subtract to get 155. Since we have no more digits to bring down, we have found that the square root of 155 is approximately 12.45.

Simplifying the Radical Expression for the Square Root of 155

Another way to express the square root of 155 is to simplify the radical expression. We can do this by factoring 155 into its prime factors: 5 x 31. We then take the square root of each factor and multiply them together. The square root of 5 cannot be simplified any further, but the square root of 31 is an irrational number. Therefore, the simplified radical expression for the square root of 155 is √(5 x 31) or √5 x √31.

Graphing the Square Root of 155 on a Number Line

We can also represent the square root of 155 on a number line. We start by drawing a number line and marking the integers from 0 to 13. We then estimate where the square root of 155 would fall between two integers. Since we know that the square root of 144 is 12 and the square root of 169 is 13, we can estimate that the square root of 155 is between 12 and 13. We can then mark a point on the number line between 12 and 13 to represent the square root of 155.

Real-Life Applications of the Square Root of 155 in Measurement and Distance

The square root of 155 has real-life applications in measurement and distance. For example, if a rectangle has an area of 155 square units, then the length of one side would be the square root of 155. Similarly, if two points are located 155 units apart, then the distance between them would be the square root of 155.

Exploring Irrationality: Why the Square Root of 155 is an Irrational Number?

The square root of 155 is an irrational number because it cannot be expressed as a fraction of two integers. This means that the decimal representation of the square root of 155 goes on forever without repeating. To prove that the square root of 155 is irrational, we can assume that it is rational and try to derive a contradiction. Let's say that the square root of 155 is equal to p/q, where p and q are integers with no common factors. We can then square both sides to get 155 = p^2/q^2. Rearranging this equation gives us p^2 = 155q^2. This means that p^2 is a multiple of 155, which means that p must also be a multiple of 5. If p is a multiple of 5, then p^2 is a multiple of 25. This means that q^2 must also be a multiple of 25. Therefore, q must be a multiple of 5. But this contradicts our assumption that p and q have no common factors. Therefore, the square root of 155 is irrational.

Comparing the Square Root of 155 to Other Irrational Numbers

The square root of 155 is one of many irrational numbers. Some other famous irrational numbers include pi (π) and the square roots of 2, 3, and 5. Like the square root of 155, these numbers cannot be expressed as fractions of two integers and their decimal representations go on forever without repeating.

Using Estimation: How to Approximate the Square Root of 155

Estimation can also be used to approximate the square root of 155. One way to do this is to find two perfect squares that are close to 155. For example, we know that 12^2 = 144 and 13^2 = 169. Since 155 is closer to 144 than 169, we can estimate that the square root of 155 is closer to 12 than 13. We can then refine our estimate by using long division or a calculator to get a more precise value.
